Qhia koj paub qhov txawv ntawm PE cov kav dej, PE roj yeeb nkab, PE roj kav dej
PE kav dej, PE kav dej, thiab PE roj kav yog txhua yamPE tub. Lawv tsuas yog ua los ntawm cov khoom siv high-density polyethylene. Cov txheej txheem kev sib txuas kuj yog kev sib txuas kub-melt. Lawv tsis tsuas yog txawv ntawm kev siv, tab sis kuj txawv heev. Wb tham txog qhov txawv ntawm lawv.
1. Cov xim ntawm cov yeeb nkab kab sib txawv
Txawm hais tias peb hom PE kav dej no feem ntau yog xim dub, cov kab xim ntawm cov yeeb nkab sab nrauv yog txawv. Cov kav dej PE yog cov kab xiav, PE cov kav dej yog cov kab daj, thiab cov kav dej PE yog cov kab ntsuab.
2. Tus naj npawb ntawm cov kav dej sib txawv
Tus naj npawb ntawm cov kav dej PE thiab cov kav dej PE roj yog plaub, thaum cov roj kav dej tau muab faib ua cov kav dej ib txheej thiab cov kav dej. Cov kav dej ib txheej muaj ob pawg ntawm 4 lub strips ntsuab txhua; lub casing muaj 6 Green strip.
3. Lub raj xa dej sib txawv
PE cov kav dej thiab cov kav dej PE yog cov kav dej ib txheej, thaum cov kav dej PE muab faib ua tsib txheej thiab peb txheej, thiab muaj peb txheej txheej sib txawv, uas yog:
A. Cov txheej txheej sab hauv ntawm ob txheej roj kav hauv qhov chaw nres tsheb roj yog EVOH oxygen barrier txheej, txheej txheej txheej yog PE lossis PEX txheej, thiab EVOH yeeb nkab nrog kub yaj nplaum txheej yog nruab nrab ntawm ob txheej;
B. Cov txheej sab hauv yog PE lossis PEX txheej, txheej txheej txheej yog EVOH oxygen barrier txheej, thiab EVOH raj nrog kub yaj nplaum txheej ntawm ob txheej;
C. Cov txheej sab hauv ntawm ob txheej txheej roj kav hauv qhov chaw nres tsheb roj yog PE lossis PEX txheej, nruab nrab txheej yog EVOH oxygen barrier txheej, txheej txheej txheej yog npog nrog lwm txheej ntawm PE lossis PEX txheej, thiab muaj txheej txheej. ntawm EVOH yeeb nkab nrog kub yaj nplaum txheej ntawm lub puab thiab txheej txheej.
4. txawv calibers
Muaj ntau txoj kab uas hla ntawm PE cov kav dej, 32mm, 40mm, 50mm, 63mm, 75mm, 90mm, 110mm, 125mm, 140mm, 160mm, 180mm, 200mm, 225mm, 280mm, 500mm, 350mm, 300mm, 300mm 710mm, 800mm, 900mm, 1000mm, 1200mm.
PE cov kav dej yog 20mm, 25mm, 32mm, 40mm, 50mm, 63mm, 75mm, 90mm, 110mm, 125mm, 140mm, 160mm, 180mm, 200mm, 225mm, 500mm, 305mm, 300mm, 300mm
Qhov ntau thiab tsawg ntawm PE roj pipelines yog me me, xws li 63mm, 75mm, 90mm thiab 110mm.
Txoj kev sib txawv dav dav yog ua raws li cov xwm txheej yooj yim, uas tuaj yeem paub qhov txawv ntawm cov xim. Yog tias ua tsis tau, koj tuaj yeem tiv tauj cov tuam txhab ntawm PE cov kav dej, cov kav dej PE, thiab cov kav dej PE roj, thiab lawv yuav pab koj xaiv los ntawm kev xav. Koj xav tau tubing.
Vuam txoj kev ntawm PE yeeb nkab
PE yeeb nkab yog ib hom khoom siv polyethylene ua tiav thiab ua. Nws tsis tsuas yog muaj txoj kev ua tshwj xeeb, tab sis kuj nws txoj kev vuam yog qhov nyuaj dua, thiab muaj ntau yam uas yuav tsum tau them sai sai rau.
Tab sis nws tuaj yeem pom tau tias tus nqi ntawm PE yeeb nkab siv nyob ib puag ncig peb yog qhov loj, thiab nws tau ua lub luag haujlwm tseem ceeb hauv ntau qhov chaw, yog li peb yuav tsum paub cov tshuab vuam ntawm PE kav. Hnub no, kuv yuav qhia rau koj txog txoj kev vuam ntawm PE kav.
Txoj kev yooj yim ntawm PE yeeb nkab vuam:
Cov txheej txheem ntawm PE yeeb nkab vuam yog cov txheej txheem ntawm kub-melt taub qab sib koom.
Nyob rau hauv txoj kev no, ob qhov zoo tib yam kev sib txuas interfaces yog thawj zaug raug rau ib qho thermal pretreatment, thiab ces rhuab nrog ib lub phaj cua sov. Cua sov lub interface thiab txuas lub interface mus rau lub xeev ntawm viscous txaus yog suav hais tias ua tiav.
Thaum cov cua sov ua tiav, cov phaj cua sov tau raug tshem tawm, thiab qee qhov siab tau siv sai sai rau qhov sib txuas, kom cov kev sib txuas sib txuas tuaj yeem ua kom txias thiab ua kom zoo, thiaj li ua tiav lub hom phiaj ntawm kev sib txuas ruaj khov, thiab thaum lub interface yog. tag solidified ua ke, loosen nws. Lub phaj siab ua tiav.
Cov yam ntxwv thiab daim ntawv thov teb ntawm PE kav
PE polyethylene PE yog polyethylene yas, uas yog ib tug series ntawm ntau yam ntawm resins tsim los ntawm ntau yam txheej txheem, muaj ntau yam qauv thiab cov khoom thiab ntau yam kev siv. PE cov kav dej muaj xws li cov kav dej polyethylene nruab nrab thiab cov kav dej polyethylene siab, uas tau muab faib ua SDR11 thiab SDR17.6 series raws li phab ntsa tuab. Lub qub yog tsim rau conveying gaseous artificial gas, natural gas thiab liquefied petroleum gas, thaum lub tom kawg yog tsuas yog siv rau conveying natural gas. Piv nrog cov yeeb nkab steel, cov txheej txheem kev tsim kho yog yooj yim, thiab nws muaj qee yam yooj. Qhov tseem ceeb tshaj, nws tsis yog siv los tiv thaiv corrosion, uas yuav txuag tau ntau cov txheej txheem. Qhov tsis zoo yog tias cov khoom siv tsis zoo li cov yeeb nkab steel. Thaum lub sij hawm tsim kho, kev saib xyuas tshwj xeeb yog them rau qhov kev nyab xeeb ntawm cov cua kub cua sov, thiab nws tsis tuaj yeem raug tshav ntuj hauv huab cua, thiab nws yog rhiab heev rau cov tshuaj los tiv thaiv cov dej xau ntawm cov kav dej phwj los ntawm kev puas tsuaj.
Cov yam ntxwv ntawm cov kav dej PE
1. Kev tiv thaiv ib puag ncig thiab kev tu cev: tsis muaj qhov scaling, tsis muaj kab mob yug me nyuam, uas daws cov pa phem thib ob ntawm cov dej haus.
2. Zoo yoog raws: zoo yoog raws, muaj zog muaj zog, siab elongation ntawm kev tawg, muaj zog adaptability rau qhov tsis sib xws ntawm cov yeeb nkab puag, thiab kev ua tau zoo heev seismic.
3. Kev tsim kho yooj yim: Cov txheej txheem kev tsim kho yog yooj yim, cov nqi siv hluav taws xob tsawg, cov nqi kho mob tsawg, thiab cov nqi tsim nyog tau txo qis heev.
4. Lub neej ua haujlwm ntev: Lub neej ua haujlwm ntev txog 50 xyoo nyob rau hauv ib txwm muaj.
5. Kev thauj mus los yooj yim: lub teeb yuag, kev thauj mus los yooj yim thiab kev teeb tsa.
6. Zoo txaus tus nqi: zoo heev hnav tsis kam, tsis tshua muaj kev sib txhuam coefficient ntawm cov yeeb nkab phab ntsa, thiab txhim kho nruab nrab kis tau.
7. Muaj zog corrosion kuj: cov khoom siv inert, resistant rau ntau yam tshuaj lom neeg tawm, tsis muaj electrochemical corrosion.
8. Txhim khu kev qha interface: kub-melt taub qab thiab kub-melt plug technology ua rau lub zog interface siab dua cov yeeb nkab lub cev, thiab lub interface muaj kev ruaj ntseg thiab txhim khu kev qha.
